Lorann oils watermellon flavor ok for DIY?

[zoiDman]

it has the red 40 and red 3, i'm assuming not to use these for diy juices? if it had only water, PG, artificial flavor, would it be ok to use? question 2) do all flavors contain artificial flavor? or will some contain natural flavor? 1 dram of these oils are only $2 at my local bulk barn, so it would be nice if i could use the small lorann selection they do have with the glycerin they have there. If I were to make a e juice with just glycerin and a pg based flavor, would it be what is known as max VG? Thanks ahead everyone, new to the community and loving it so far.

I don't Like using Flavorings that have "Added" Colorants.

And when it came to LorAnn Watermelon, the choice was Easy. Because to Me, FlavorArt Watermelon taste better. And has No Added Colorants.
